HEAT INSULATING RECPTACLE Fiied March 12, 192e INVENTORS uR/N f.

The inside of the jarconstitutes a chamber for foodstuffs to be kept at a certain temperature. If, for example, the

jar contains ice cream bricks or other confections requiring a low'temperature7 a suitable refrigerant is placed in the jar, such as a small container of ordinary ice or so-called dry ice (solidied carbon dioxide). In one form of our invention, the dome of theY inverted jaris used for the storageof dry ice,`

which is held on a porous or perforated disk suitably supported.- 4The cooled confections are removed from the inverted jar in any practical way, either'by dispensing vmeans 0r 'by simply lifting the jar.

In a simplied form of our invention, a double-walled vacuum jar of Pyrex glass or other suitable material is placed in inverted position on a basewhich may have a cush-' ioning ring or disk to receive the lower edge of the jar. The walls ofthejar project outwardly at the mouth to form an annular flange or shoulder which rests on the base. A ringhaving an inturned flange at the top is mounted onthebaseyand this inturned iiange engages the outer flange'of the jar,- whereby the latter is firmly held 'in inverted v position. A washer of cork, rubber and the j like is preferably placed between the ringand the jar to prevent possible injury tothe latter when theringis forced into holding engagement with the flange of the jar.

In a preferred embodiment of our. invention, the iianged ring that holds the inverted 40 jar is -rotatable on a cylindrical base. to

ywhich it is removably secured by'ba'yonet` v slot joints or likeY connections. Asuitable support inside the jar rests on the baseyand the top of the support carries a plate or-disk which partitions olf the'spherical domeof the jar to form aV chamber fordry ice. Thisr v construction is shown by way of example in` the .accompanying drawing; whichfis partly' in elevation and partly in section for clearness. A

cylindrical extension 13 on which the. jar-55 rests. The mouth of the double-walled vacuumfjarlO'is formed with anintegralange 14: which extends outwardly to forman annular seat orv Ishoulder r15. If desired, a cushioning disk or washer 16 may be placed o0 onV the.v base toV receive the flanged mouth of thejar.V j f jj j A cylindrical ring 17'is' rotatably mounted on thefextension 13 of base 12,'and is formed c at the top with an inturn'ed liange'lS ar-l 65 ranged to engage the annular shoulder 15 of jar y10. 'ring 19 ofcork, rubber or'the like,may be interposed between the'flanges 15 and 18 to prevent possibleinjury to the jar..

when the ring 17 is tightened. Any practical 70 connection may be used for adjustably mounting the ring 17 on base 12 so as to clamp the jar in position andv release it whenIdesired. In Vthe drawing we haveshown the. cylindrical base portion 13 provided "with 75 pins 2O arranged to .enter bayonet-*slots 121 in ring 17. The inclined portions 22 of slots j 21 act like screw-,threads for tightening and loosening the ring relatively :to the jar 10.`

Itis clear that when the ring 17 is turnedv 80 yin the` direction of arrow a, the `inturned `fia'nge 18 is forced down against the annular shoulder 15 (or the interposed yieldable ring 19K) whereby the inverted j aris rigidly `clamped to the base; .When theirin'g is 85 turned the Vother wayuntil the pins V2O. encounter the open vertical endsof thebayonetslots'21, the ring is disconnected from thebase and can be lifted over the jar 10,*so .that'the latter is now free to be tilted or removed.

Infasse'mbling the parts abo-ve described, the jar 10 is 'placed inverted on the base portion 13,'"the yieldablewasher 19 (if one is used) is put on the annularflange or shoul-- der 15 of the jar, andV finally the fastening "95 ring 17 is lslipped down over the jar and se. cured Vto the base. vIn' 'the broader aspect of* our invention,` the ring 17 may be' connected to thebas'e in any other practical way.vv g j The outer y'wall -of`j ar 10 has aprojecting wo to which it is cemented in any practical way.

There are several kindsy of cement on the market for use on glass. We have used sili-V vcate of soda with goodresults. yThe spherical dome space 28 ofthe invert- .ed jar is utilized as a storage chamber for dry ice or other ksuitable refrigerant 29.; For thispurpOse apervious Ydisk 30 rests on a f suitable-support,- which in this instance con- -sista of a palr of inverted U-shaped strips3l.

As eX- amples of such material we may mention .Wood pulp, porous cement, perforated-cork or metal, and others Valong the same line. The escape of refrigeratinfr gas from chamber 28 may alsobe elected liy so shaping the .disk vthat. it docs not close against the jar all the way around, thereby providing passages for the gas. It will be noticed that the supporting legs 33. take up practically no room and leave 4the compartment 34 unobstructed for'storing foodstuds and other articles thatmust be kept cold. If desired,

a suitable container lmay be placed on disk 30 to hold the ice dry in tightly packed form.

Any other practical support may be used for disk 30, asfor .instance a central rod secured atits lower end. to the base and carryingthe disk at its other. end. Manifestly,lthe dome `chamber 28 could also be used to store va source l,

of heat' if the jar is tokeep articles hot` In removingl or dispensing the articles from compartment 34T, thev j ar 10 may be lifted or .tilted at the bottom, or suitable delivery vmechanism may be associated with the jar.

We have not deemed it'necessary to show or describe anyv delivery or ejecting mechanism,
